Decoupling Control of Traction-and-guidance in Bilateral Air-core Linear Synchronous Motor

Bilateral air-core linear synchronous motor， mutual inductance gradient， decoupling of traction and guidance， ultra-high-speed maglev.

In this paper,the electromagnetic force model of the motor is established based on the mutual inductance gradient of the coil.By analyzing the relationship between the electromagnetic force, electromagnetic gap and d-q axis current,a decoupling control method of traction-and-guidance in bilateral air-core linear synchronous motor is proposed.This method realizes the independence of motor lateral movement and traction movement.Its effectiveness is verified by simulation, which provides a method and idea for the guidance control of the motor under ultra-high speed operation and other industrial applications.
